Systematic Inclusion of High-Order Multi-Spin Correlations for the Spin-121\over2 XXZXXZ Models

We apply the microscopic coupled-cluster method (CCM) to the spin-$1\over2$ $XXZ$ models on both the one-dimensional chain and the two-dimensional square lattice. Based on a systematic approximation scheme of the CCM developed by us previously, we carry out high-order {\it ab initio} calculations using computer-algebraic techniques. The ground-state properties of the models are obtained with high accuracy as functions of the anisotropy parameter. Furthermore, our CCM analysis enables us to study their quantum critical behavior in a systematic and unbiased manner.Comment: (to appear in PRL). 4 pages, ReVTeX, two figures available upon request.

Labor Law-Unemployment Compensation-Applicable Disqualification Provision Where Claimant is Discharged for Unauthorized Walkout

Plaintiff was discharged by his employer for participating in a walkout which was not authorized by the union of which he was a member and which was in violation of the applicable collective bargaining agreement. In passing upon his subsequent application for unemployment compensation, the Appeal Board ruled that he was disqualified from receiving benefits for the duration of his unemployment because his actions had constituted misconduct under section 29(1)(a)(2) of the Michigan Employment Security Act. The circuit court reversed, holding that the misconduct provision did not apply and that plaintiffs acts were properly cognizable under section 29(1)(b) which provides for disqualification from benefits only for the duration of the labor dispute in which a claimant is engaged. On appeal, held, affirmed, two justices dissenting. Where a claimant is discharged for labor dispute activities which violate a collective bargaining agreement, the labor disputes section of the Employment Security Act governs rather than the misconduct section.
